Amazon Personalize offers a machine learning technology that gives real-time recommendations in a flexible and manageable environment. Personalize lowers the barriers of entry for companies that are interested in leveraging machine learning power. It’s a fully managed service, meant to be used by competent technologists, but no machine learning knowledge required. Rather than requiring months to implement, in just a few hours you can go from clean data to recommendations; in a few days, you can have usable models.
